I want to create a website to record my rambling groups' routes.
Linking into OSM is easy but I have yet to find a way to overlay our track onto the OSM map. It would be even better if I could use Bing in this endeavour.
Has anyone done this already? If so please let me know.

For manual creation of an image with your route overlaid.
An application called Mobile Atlas creator http://sourceforge.net/projects/trekbuddyatlasc/ will be able to create a map and output it as a kmz file, or a .png file with a calibration file (for oziexplorer)

For sharing your route on the net.
For websites, there's bikemap.net which will let you share your routes and the user can pick the OSM or Opencyclemap as the background that the route is printed over.
I like Opencyclemap as an overlay, as it lets you see topo lines of the ride. The downside is that the opencyclemap server is owned by one guy, and he needs help scaling things up to handle the traffic, or help paying for the overhead.

If you don't want to deal with any JavaScript then alexz provides good links. Or if you want someone to build a system for you, I'm available for hire from March.

In what way do you want to use Bing? You can't use Bing imagery unless you get a license from them (think money). OpenStreetMap only has s a license/agreement to use their aerial imagery in our editors for improving OpenStreetMap. If you want to use the mapss, then that is doable I think but you might need to use their API and get that to work with an OpenStreetMap option.

Also alexz, I don't think Andy Allan (the very clever guy behind OpenCycleMap) needs any help in the technical sense. But cost, yes, is an issue with map tiles and traffic. I think because of bandwidth. Andy is a nice chap so he'll be happy if you talk to him and discuss stuff before loads of people start using his tiles via your site.

Final pedantic point, OpenCycleMap is not an overlay it's a base map. An overlay would have a transparent element so you can see some image/map underneath it. Rather your tracks would be overlays that you see placed over the OpenCycleMap/OSM base map.

Thanks for the information, ladies and gentlemen.
I'll have to work through the info you have provided and see if it will cover my ideas. I don't want to start bei copy OSM-data to a png or jpeg but want to link in to the current osm data and add my track as an overlay so that the club ramblers can see where they went and when they went. I also want to link to the town/restaurant websites on the rambling route but this it no problem for me.
Thanks for the info on Bing: Charges. I'll forget that idea!
If any more ideas are out there. I'll be pleased to hear of them!
Thanks again

I forgot to add that I have foreigners who would like their offspring to see where they are going along with the above mentioned towns/restaurants and other pertinent links. It saves doing a lot of work this way.
